Contamination control breather



FIG. 1 is a side top perspective view of a contamination control breather showing my new design;

FIG. 2 is a side elevation view thereof, the opposite side being a mirror image thereof;

FIG. 3 is a side bottom perspective view thereof;

FIG. 4 is a top plan view thereof;

FIG. 5 is a bottom plan view thereof; and,

FIG. 6 is a side and top perspective view showing a second embodiment of my new design.

The broken line showing of environmental structure in FIGS. 1, 3, 5 and 6 is for illustrative purposes only and forms no part of the claimed design. The cross hatching represents a mesh screen and is understood to extend uniformly throughout the area represented. The opposite sides and top and bottom of the second embodiment are identical to those shown in FIGS. 4 and 5 and the side opposite that shown in FIG. 6 is identical to that shown. 

I claim the ornamental design for a contamination control breather, as shown and described.
